Assertion : The refractive index of diamond is `sqrt(6)` and that of liquid is `sqrt(3)` . If the light travels from diamond to the liquid, it will totally reflected when the angle of incidence is `30^(@)`.
Reason : `mu=1/(sin C)`, where `mu` is the refractive index of diamond with respect to liquid.

Options

A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B. If both Assertion and Reason are true but Reason is not correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is true.

Answer

D

Explanation

(d) For total internal reflection the angle of incidence should be greater than the critical angle. As critical angle is `35^(@)`. Therefore, total internal reflection is not possible.
